Fund-raiser boarding vehicle, one alongside a restaurant (9)
I believe the answer is:
cafeteria
'restaurant' is the definition.
(I know that cafeteria is a type of restaurant)
'fund-raiser boarding vehicle one alongside a' is the wordplay.
'fund raiser' becomes 'fete' (I can't justify this - if you can you should believe this answer much more).
'boarding' is an insertion indicator.
'vehicle' becomes 'car' (car is a kind of vehicle).
'one' becomes 'i' (Roman numeral).
'alongside' says to put letters next to each other.
'fete' inserted into 'car' is 'cafeter'.
'cafeter'+'i'+'a'='CAFETERIA'
Can you help me to learn more?
(Other definitions for cafeteria that I've seen before include "Canteen" , "Place to eat" , "where food is served" , "Where one scoffs" , "Self-service eatery" .)
